Today I found PureCM Client refusing to open Submit Changeset window without any reason. The only effect of issuing Submit command was new entry at system’s taskbar.
It showed title “Submit” but without any context menu nor possibility to play with.
Finaly I found the method to force PureCM to behave as requested. It turned out that it stores last positions and states of any window open. Somehow entries for my missing window become damaged or invalid.
I found the registry key which seemed to hold the data:
HKEY_CURRENT_USER\Software\PURECM Client\Dlgs
and “fixed” it by deleting it. After reopening PureCM client everything went back to normal.
