Sudden slow executing files in FreeCommander

[AWE]

Hi, I have FreeCommander 2007.10a
I have troubles with starting programs / files.
When I start FreeCommander and click on eg. *.cdr file everything is fine - CorelDraw starts and it reads the file I clicked on.
After working with file in Corel I save it and close it.
Then I do it in FreeCMD again with anoder *.cdr file and so on... (it can by any file, not only .cdr)
After starting couple these files, one after another, suddenly it becomes very lazy. It takes at least 30 sec to open file and it doesn't matter if i click on it to run the file or press enter.
Restarting FreeCommander won't help, I must restart PC.
I am using it on FSC Amilo Pro with Core Duo T2350 and 1GB DDR2, Windows XP pro SP2. I have tried it on different PCs and laptops and it behave in the same way - I have also tried some older versions and I wonder I couldn't find this bug here described. This is the ONLY bad thing in excellent commander.
Please, can U help me?
I do not use any plugins, I only use CZECH language.
