Toolbar Lock-up

[JohnB]

Hi,

I have automated the opening of Word documents. From a VB
menu application, the user clicks a Word document (link to
a file) and then it opens in Word.

This works OK 99% of the time. However, sometimes after
opening, the tool bars and menu bars 'lock'. I cannot
click them. The document is loaded OK, and I can type
text. If I switch to another program by clicking on it on
the task bar, and then return to Word, the tool bars are
unlocked and everything is fine again.

Ideas anyone?

Thanks,
John
