ID's greater than 33,000 now should work for all libraries

Optics DB path is now remembered in File/Preferences

Program doesn’t crash when accidentally opening an Optics database as a WINDOW 5 database

Fixed memory leaks -- one related to THERM temperature profile data and one from repeated open and closing of databases

Opening a recent file no longer causes the current file from not appearing on the recent file list

Reports should now print properly with the Microsoft XP Operating System

When the Nominal Thickness preference is changed, all results (both window and glazing system) are invalidated and must be recalculated

Going from List to Detailed view in the glazing system library is no longer slow

Added Export function to the SHGC0/1 and VT0/1 Details dialog box to export the results to a CSV file.

Temperature map now displays properly

Dewpoint temperature in CI Details view now displays in the units that the program is in (either SI or IP -- used to only show SI)

Angular data is now correct in the Window Library detailed report

3 decimal output for SCc, SHGCc, and VTc for Glazing Systems in the Window Library detailed report

Energy Plus reports now work properly for windows with two glazing systems

Relative pathnames no longer cause Temperature Map image to fail

Minor format changes to the Window Library detailed report

Added a Color Properties Tab which displays L*a*b*, purity and dominant wavelength

A warning is displayed at Calc time if there are glass layers that do not have spectral data

Optics standards files that don't have color or UV methods now generate warnings, rather than errors, and set those values to "N/A"

Occasional non-responsive glazing system layer spin button fixed (this happened when you changed another field first (e.g. comment) then directly hit the spin button.

Added name of spectral data file if one exists in the glazing system section

Added New, Copy, Delete, Save and Report buttons to all the Library Detailed view

Added ability to import and overwrite protected records with protected records from another WINDOW5 database

Added a database “Compacting” feature in the Tools menu, which is useful when records have been deleted.

Added a tab in the Results section for Angular Data.

Added a Glazing System Report (similar to that in WINDOW 4.1) which includes the angular dependence table and the temperature information.

Added damage weighted UV Transmittance calculations for both Krochman and ISO methodologies

Implemented a checksum feature, at both glass layer import and also at calculation time, which checks to see that the spectral data in the Glass Library has not been altered from that of the International Glazing Database. If the checksum does not compute correctly, WINDOW will automatically remove the # value.

Conductivity of the glass layers from the International Glazing Database have been set to 1.0. This will minimally  change the U-factor calculations.

When importing records from the International Glazing Database, the IGDB version number is displayed.

Reads Optics 5.1-format databases

Added ability to change the ID of a record imported from the Optics5 user database.

Changed what the program pre-pends in the Source field when importing records – importing from the International Glazing Database pre-pends “IDGB < db version #>”, importing from an Optics5 user database prepends “IGDB User”.

The gas properties reported in the DOE2 report are now correct

The THERM file paths are now relative to the currently open database (MDB) file.

Improved the speed of importing THERM files.

Fixed a problem for Microsoft Windows XP and 2000 operating systems that caused a large increase in memory use when importing THERM files.

Fixed a crash when going from the List View to the Detail View
