Nevermind.. I thought that fixed it.. It made it a little better. Going to work on the other context menu entries to see if those are the cause.

I fixed it!! It was a thing called Coolplayer. It's a tiny little MP3 player, and I removed all the registry settings for its context menus.. After I rebooted, I tried a file>open in Paint.net and had no problems. Thanks for all of your suggestions!

When I open a file using the method ibelow, I have no problems opening any type of file... Right-Click on the file in explorer, select "open with" and browse to C:\Program Files\Paint.net\paintdotnet.exe So I don't know.. Maybe I just do it this way for the time being- but it would be nice if someone could give me a fix for this.. Thanks, Jeff

Here is what it looks like when I double click on a file.. The file list disappears, and any Windows open in Paint.net go blank.. At this point my cpu utilization jumps to over 90%.. And bounces between 75 and 90+%.. Check the attached image..

Thanks for the suggestions, but it appears that no matter WHICH folder I naviagate to, as soon as I try to double-click a file to open it, Paint.net locks up after the double-click. Right now, I just went to My Pictures, tried to open a tiny jpg of homer simpson and all it did was lock up. Now if I ALT-TAB, Paint.net is not one of the ALT-TAB icons available, even though "Untitled (100%) -..." is still on the taskbar (from Paint.net).. So it appears the program is there, but not really there, or something. If it's not available as an ALT-TAB option, what could that mean? I might try to uninstall, delete the Paint.net folder, run CCLEANER (a registry/system cleanup util) and try to install this again.. I'll let you know if that does any good.

Yes, it's the Desktop.. Though i believe any location will lock up, I know for a fact that the desktop is a problem.

Yeah, tried it.. No matter what file I try to open with File > Open, it just hangs after double-clicking on the filename, requiring an End Task on Paintdotnet.exe Print-Screen does nothing when it locks.. BTW I've tried uninstalling and re-installing, to no avail.

Nope, this is during File > Open, not File > New.. That trick didn't work.

Hello, when trying to open files using File > Open in paint.net v3.10 and the version previous to it, Paint.net locks up, and just sits there.. When I vew its activity in task manager, Paint.net is using 76% to over 94% of the CPU. It hangs for quite awhile before I decide to end the program through task manager. This has not always happened to me- I'm not sure when it started. I used Paint.net about 4 or 5 months ago with no such problems.. When opening a file using Explorer (right clicking on the file and selecting "Open with Paint.net") this does not occur. Any help would be appreciated.. Thanks!
