Is there a way you can clear your cache memory (browser memory first, of course) and re-enter your website PWs to see if the cleared memory might enable the FM9-Edit to work quicker? With Windows, you might also need to do a hard drive defragmenter, so as to organize and save on HD memory...sometimes if either cache or HD is "full" or "disorganized" putting things in order can help improve a computer's performance...
Although I'm no techie, that, plus a restart, might be the smart thing to do...short of calling tech support and asking how to help lagging applications work better...
