I have an application which can be compiled and stable using Delphi 3. When I work with the application using Delphi 4.02, I have intermittantly lots of access violation errors. It seems it may be related to a certain practice in this source code where there is something interesting:
The greatest problems seem to be surrounding these forms like those in file3.
Tried under Win98 originally
Moved to NT4 SP3 and problem is still happening!
Some simple custom components were used but they were reliable under Delphi 3. The third party controls which were used are the ones intended for Delphi 4.
