ShowModal doesn't return to calling window
Posted on 2011-03-25
We have an app written in Delphi 7 that is used by about 1400 users. In a small number of cases (5 or 6) the program is not behaving properly when performing a ShowModal. We have the situation where the main form does
then FormA does
then FormB does
You would expect then that when FormC does a Close, it should return to FormB. However what these users are getting is FormA is shown and FormB is buried underneath FormA.
Two questions then: Can anyone explain why this is happening on a limited number of machines?
Is there an easy way round it in the code? I've thought of putting Show for the calling form after every instance of AnotherForm.ShowModal but I'm not convinced this would work and as the overall project is more than a million lines long it would be a tedious task.
I believe in all cases the users concerned have Win XP Prof.
