[WriteLog] writelog sticks with a lot of qsos

[Kostas SV1DPI]

I have noticed that writelog sticks momentarily sometimes. I have 
noticed it happening after 1000 qsos in the log. It happens on cw and 
rtty. On cw while I hit the function key, I am waiting for 1-2 seconds 
to start sending. On rtty it starts keying something like RY for a while 
and after 1-2 seconds the message starts. It happens after some hours. A 
fresh reboot corrects the problem for a while but it happens again. The 
result of this is that I use the wintest the last time for cw contests 
but I prefer writelog. The biggest problem is that I noticed it on rtty 
also the last time...
Is anyone other who has noticed this behaviour?
The keying device is microham in the first radio and winkey plus 
homemade interface to the 2nd radio (I don't think the problem is in 
hardware as it works fine with wintest and dx4win). Computers are in 
network and I use the 11.28 version but I have noticed it in all of the 
last versions. Computers in the shack are duo-core with 2gb memory and 
windows 7. A 3rd laptop is used for backup and runs the clusters.
I can not reproduce it in my home computer. I believe this is why the 
computer is not so many hours on or the clusters spots are no so many. 
My first thought was that heavy spots from the clusters was the cause 
but on rtty I had not skimmer on and the spots were much lower. I talked 
it with a friend of mine who runs a much older version of writelog and a 
new computer with lot of memory and he has noticed it also. This is why 
I am asking for comments...
