I believe it may be an issue with my UEM. I just sent an email to IDM Support. I have a whole new issue now. Laying it out below in case anyone can help/experienced the same issue:
I was running into the issue that I'd set templates up, add them manually, up to about 20, then set the hot keys for the 10 that I can. When I quit UEM and then reopened, all the templates were gone. I did this about 3 times before I thought maybe there was an issue with the UETMPLTE.DAT file. So, I tried to open, reenter the templates, and before closing, opening up the user/Library/Appliation Support/UltraEdit file and creating a copy of the UETMPLT.DAT file, saving it on the desktop. Opened, UEM, no templates. Closed UEM, opened the UE file, dragged the backup copy into the folder, replaced the current one, and opened up UEM. Nada.
So, I deleted the UE app, deleted the UltraEdit Application Support file, and redownloaded, reinstalled. Opened the app, no templates. Checked the UE file in Application Support file, no UETMPLTE.DAT file at all. Decided maybe this is how it started: with no file. Added my templates, checked the folder agin, there it was. Voila! Problem fixed! Or so I thought. Closed UEM, opened UEM, no templates. Template file is still there.
Anyone else ever have this problem? Templates just don't seem to want to work with my UEM/machine.
Again, running UEM 220.127.116.11, and OSX 10.7.3. This is a 2010 MBP that just had the OSX completely reinstalled.
