If HTML TADS crashes, particularly when you select the "Options" item of the "Edit" menu or "Customize" on the "Themes" menu, you probably have an out-of-date version of a Windows system file called COMCTL32.DLL. If you encounter this problem, you can fix it by downloading this file from the Microsoft web site:
ftp://ftp.microsoft.com/softlib/mslfiles/com32upd.exe
After downloading the file, double-click it to run the installation program, which will install the upgraded DLL for you. Note that HTML TADS automatically checks to make sure you have the correct version installed and warns you at startup if you don't. Although you can choose to continue running if TADS displays this warning, we strongly encourage you to upgrade your COMCTL32.DLL before running HTML TADS.
