Do you know what this means in terms of getting it to work in normal mode? Thanks, Sheila
Well unfortunately it just means that you've narrowed down the causes a little, I suggested that simply to find out if TC works ok with windows core program, being that it does then I wouldn't bother reinstalling TC anymore, your probably just wasting your time, do you normally work with a network connection, or a backup drive, If it was me I'd.
Disconnect from any network / try TC saved to local drive only,
Try a program like LockHunter, http://lockhunter.com/index.htm
this may help identify if some other program is holding onto the dwl file and preventing TC from updating it, basically one installs LockHunter, start TC, draw something, save the file, then whilst still open, use windows explorer to navigate to the dwl file (with the same name as you just saved), right click file and choose 'what is locking this file', you don't have to delete anything just see what it says, if only TC is shown then close Lockhunter, save the file a second time, it saves as a new temp name, see if the original dwl is still there and recheck it, unfortunately I'm running out of ideas, you could try
Turn off antivirus & firewall / try TC
Turn off other programs like windows defender, mailware / try TC
if your the only one who uses the computer, you could ask Dave Taylor if there is a registry hack that will turn off the dwl creation - at least that may get you working again.
As a test you could use LockHunter to try and delete (unlock) the dwl file before you save the TC file a second time, if that works you are certain the dwl is causing the problem.
Sorry I can't really provide an answer, but some problems are really just trial and error to locate.
