Update: What I tried to explain is that: In the computers that only has Ethernet active and Airport turned off, it does't happen. The issue only happens in the computers with Ethernet and Airport active and connected.
Thank you for your post.
Although I have found a copy of FileMaker Pro 6, I am unable to find a copy of FileMaker Server 5.5.
With FileMaker Pro 9 and FileMaker Pro 10 (the current version), I am constantly connecting to FileMaker Pro files hosted on FileMaker Server, and I have yet to crash.
Is anybody else out there with FileMaker Server 5.5? Any similar problems?
We were running FMS5.5 and FMP6 on Mac OS 10.3.9 and 10.4.11 computers, until upgrading to v9 last year. I'm sure many of the iMac computers had their Airport turned on, but not connected to anything. So, do your computers connect only through Ethernet, or do you also have a wireless access point?
