I've been having this issue for a while now (several months) and have just been working around it but I thought I may as well post here and see if someone can help...
If I attempt to execute a program with an error (eg. from a test window), I get the error message and the option to "View program sources of error stack?". If I choose Yes it opens up an error stack window but instead of showing me a trace of all the affected programs, it shows me 3 tabs with question marks (?) as the title, followed by a final tab with my original command from the test window. The first three tabs are completely unrelated create statement from months (possibly a year) ago.
Where are these coming from and how can I clear them?
Thanks
