I am getting a strange error message: "Project e:\robb\slickbugs\" should have .vpj extension.
To reproduce (in Windows):
1) Get the file swbug.7z from support.slickedit.com
2) Unzip its contents to e:\robb\slickbugs
3) Project->Open Workspace: e:\robb\slickbugs\StackWalker.vpw
4) In the project tool window, under "Header files", find "StackWalker.h" and press DEL to remove it from the project
5) Go to project properties, add files, add StackWalker.h back into the project
6) When pressing "OK" in project properties, that is when I get the error message.
I am using 21.0.2 on windows x64 with hotfix_se2102_11_cumulative.zip
Thanks for taking a look!
