Alan,

I've only got my one PC. Last week I installed FB 1.5.1 over 1.5.0
after shutting down 1.5.0. I could try completely removing and
reinstalled 1.5.1. Recommended?

As mentioned, I've got a single 6.6g .FDB file. In a previous thread
I started last week, this shouldn't be a problem under XP/NTFS. For
the hell of it, last night I reimported my data into a recreated
database that's broken down into 2g segments. Data imported fine, but
I'm still having the same query problems.

I'm 2 days behind where I should be, and after numerous successful FB
projects (albeit much smaller databases), I'll have to switch over to
MySQL as I'm frustrated as all get out and can't spend any more time
troubleshooting. I'm, unfortunately, VERY disappointed with FB at
this point...
