FYI ~ TDriveComboBox Fail on form delete

This is for information sake in case anyone has encountered this issue.

C++ Tokyo Builder 10.2 Version 25.0.27659.1188 / Update 1

This error refers specifically to the Win 3.1 TDriveComboBox component where upon deletion the form in the form designer will stop responding to edits.

To create the error start a new VCL Forms Application project.

From the Win 3.1 tab of the component palette find the TDriveComboBox and place one on the form. Run the program, do not mess with the combo box at all, and just close the program with no other action like resizing it or moving it. Now you are back to the form designer. Delete the combo box by selecting it and pressing the delete key on your keyboard.

Now attempt to resize the form window (not the designer).
On my machine I get Access violation at addy / write of addy - close the error window.
Attempt other things including closing down the ide and quitting the compiler.

And that's all - I'm just wondering if anyone else gets the same results.

Thanks for your time.
