>>I have a form with a command button that uses GETFILE() to allow the user to select the filename of a document. There is a second command button that is used to view the file (with either Envoy or Acrobat, depending the file extension.)
>>
>>On my development machine, the following steps cause the file locator button to do NOTHING:
>>
>>1. Use the file selector button to select the filename and store it to the textbox.
>>2. Use the view document button to launch the appropriate program (via RUN).
>>3. Attempt to use the file selector button again.
>>
>>If I stay off of the view document button, I can repeatedly use file locator with no problem.
>>
>>When I say that the file selector button does nothing, it depresses, but no actions take place. I can quit the application and wind up back in VFP but then I can no longer DO anything or BUILD APP.....
>>
>>The strange thing is - the buttons all work just fine on the other machines that do not have VFP installed when the exe is run.

>>Help??
