wfica32.exe consuming too much memory, in the Citrix XenApp / Presentation Server forum on BrianMadden.com

Has anyone else noticed that after launching the ica client, when wfica32.exe loads, that the memory on the client (wfica32.exe) continously rises and doesnt let go even after closing applications. For example, I can launch the client, then from within my ica session I open Internet Explorer. Wfica32.exe on the thin client in this case, goes up by about 320k. Then, for every other instance of IE that I open, another 320k of memory is called up by wfica.exe. When I close the IE instances, the memory used by wfica32.exe remains, it doesnt go back to what it started with. Eventually, my T5720 with 256MB of flash memory runs out, causing other services to fail. I dont get this result with any of my other thin clients, be it 128MB of flash or 1GB of flash. They do accumulate memory, but never crash. I forgot to mention that we are using the Citrix Metaframe Presentation Server version 4.0 and client version 10.2, 10.150 and tested with 9.0. Also, our thin clients are connecting via web interface. One more recent thing I noticed, is that if I minimize the ICA client, the memory used by wfica32.exe drops down to about 2000k, but when I bring it back up the memory goes back to what it was using, unless I first close all instances of IE prior to minimizing, then the memory goes back to about 2000k after restoring the window.
