I have uploaded the file TIBCtrlGridBug.zip.
1. Open the project.
2. The MainForm is shown by default.
3. Use Shift+F12 to open Form2. This form uses multiple
TIB_CtrlGrids with the DataSource property set.
4. Add either a TIB_Memo or a TIB_ComboBox (with Style of
csDropDownList).
5. Use "Close All" to close the project and save your work.
6. Reopen the project.
7. Use Shift+F12 to open Form2 and recieve the error "Error creating
form: Cannot focus a disabled or invisible window".
8. Use "Close All" to close the project.
9. Reopen the project.
10. Use Shift+F12 to open the data module first.
11. Use Shift+F12 to open Form2 without error.
The problem appears to be opening a form with the specified elements
(TIB_CtrlGrid with DataSource set and TIB_Memo/TIB_ComboBox (with
Style of csDropDownList) when the currently focused form has a
TIB_Dialog (note the TIB_StatusDialog on the MainForm).
Focusing on a Form without a TIB_Dialog prior to using Shift+F12 will
allow Form2 to open without error.
Removing the TIB_Dialog from the MainForm will allow will allow Form2
to open without error.
Thanks
