Amen to that.

I have an ongoing similar problem.  After Quanta has been running for a 
while (say an hour or so, though I often leave it up for days), 
switching from one file to another begins to take a long time.  Opening 
a new file occurs quickly, but I am still unable to do anything with 
that file, or change to another one, for periods of about 30 seconds 
(that's an estimate - I haven't timed them).

This seems unrelated to system resources (e.g. at the moment there is 
about 1.1 GiB of memory available, and 1.4 GiB of swap), CPU usage, or 
the size of the files (it is as likely to occur with a few small files 
as with a few large ones - though I have few truly large files).  I work 
on both PHP and HTML, with more of the former, and they are usually 
relatively small.

The only solution is to kill all the files and restart, at which point 
everything is hunky-dory for a while.  Once in starts again, there does 
not seem to be a cumulative effect, but I say that not having actually 
timed anything.  I do have other programs running: Firefox, Thunderbird, 
Openoffice, gpdf, Konsole, gnucash, gkrellm, exim4, dovecot, plus the 
usual suspects.

If it helps, I have a Debian testing system, which means Quanta 3.5.2.

I think I covered your questions.
