Shellexecute Twice For A PDF ?

[adamwill]

We have a form in our VFP8 app which we use for launching PDF's via shellexec. For some reason (on some machines) we have to click twice for the PDF to appear. After the first click the PDF does not appear on screen (though it can be seen in task manager), after the second click it appears. This might not seem a huge issue - but our customers are less than happy.

Does anyone have an idea of any settings which might be the culprit?

Can you post the line of code you are using for ShellExcete? What parameters are you using?

I tried the code suggestion and it had the same problem. I have however disovered that the only machines it seems to work on are running acro reader V4 and not V6. So as long as the documents are compatible that is a sort of solution.
