Thank you for your post.
There has been some problems reported with the new Safari 5, but those problems pertain to PDF files being attached to emails. I have not encountered any problems with FileMaker Pro 10 not launching.
Has there been any other applications or system files installed other than Safari 5? Are you able to revert to Safari 4.0.5? Any other information you can provide may be helpful in narrowing down the problem further.
Thanks for your reaction.
No, nothing else was installed.
To revert to Safari 4 is difficult , but with Timemachine active I can go back in time.
But I have a workaround: each time before staring FM I delete the Filemaker Prefs in Library.
It works but it's not normal
Thanx for your reaction.
I find out, that the screen do you want to update to FM 10 was the problem. I reacted no, and don't ask me again, FM cannot start was the result. I tried the answer yes, than there is no problem to start FM. To be sure I repeated it several times.
Now with the update to OSX 10.6.4 , with Safari 5.0 in it, the problem is solved.
Was it a bug in Safari?
