I have created a custom screen using asp.net and have a drop down list control on it. The issue is that I am having is that I am unable to select any of the list items when I am in Tessitura using the mouse. I am able to do everything I need to when I am in debug mode and also when I hit the page from a browser. One thing to note is that while I am in Tessitura, if I get the drop down list to have focus, I then can use the arrow keys to change list items just not by the mouse.
Any ideas?
Thanks,
Marty
This is an issue with the manner in which dropdown SELECT controls are rendered, detailed in Microsoft's Knowledge Base at http://support.microsoft.com/kb/927377 (yes, it's been around since IE 7, and it's 'by design').
You can correct it by adding an entry to the registry (on each workstation) under the following:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ Main\FeatureControl\FEATURE_USE_WINDOWEDSELECTCONTROL
If Office is installed, you'll see entries in that folder for Excel, Word, etc. Create a similar entry for "tessitura.exe", REG D_WORD, value 1.
Hope this helps!
