Is there vba code which can disable/enable switching between open workbooks

Hi all,

I have some code which after being run seems to disable the ability to switch between open excel workbooks either via alt-tabbing or clicking on a non active workbook from the windows taskbar.

I'm hoping to find some code which will enable this ability again to use as normal.

If i click on the restore windows button (button left of the lower close windows button) in the active workbook i can then see and switch between open workbooks.

Any ideas?

i'd prefer to not paste in the code as it runs into the hundreds of lines and will save me from editing out sensitive code

anyone?
