Jon,

Can you close DF, restart it, let it run for 1 minute then post another screenshot from Process Explorer? I'd like to compare the 2. Thanks!

Not much better - it starts out initially running with 577 MB virtualized, and after about 15 seconds it jumped to the 606 MB value.

Unrelated question: I don't see the x86 hook exe file listed below the main exe - do you have both hooks enabled on the Troubleshooting tab?

Nope - I don't use the KB shortcuts (strangely enough, as I am usually a kb junkie) so I disabled that hook too.

I have just installed the W7 Final release so I am about to re-install DF (finally!). I'll leave the KB hooks in place this time Jon and see if that makes a difference....

Nev - I wonder if it is b/c of settings we have or our computer setup....

Care to post your hardware specs?
I am I.

After doing some reading on this issue, it seems like it really isn't an issue at all. Let me try to explain, and feel free to jump in and correct me if I'm wrong. The "private bytes" column is the actual measure of how much memory a process is using. The "virtual size" column is a measure of how much space is allocated (but not necessarily being used). A process on a 32bit version of Windows can have a virtual size of up to 2GB. In the first post, DisplayFusion is actually using ~50MB or RAM, but for some reason it has told Windows that it might want to use >600MB in the future. This is nothing to be concerned about, as it's not really using that memory. If the "private bytes" column sky-rockets then we have some cause for alarm. I hope this is clear, please let me know if you have any questions, but I'm going to mark this topic as "complete" for now. Here are some additional resources:

sounds right to me. When you do a Pascal Ansistring it reserves the memory without actually using it.

Makes sense to me as well. Thanks for investigating, Jon.
