Weird thing I’m running into, when I use the Poloygon Lasso Tool, both my CPUs are pegged at 100%. When I switch tools, it goes back down to the normal 1-5% on each CPU.

This makes the selection all slow and jerky, thus making it impossible to work with this tool.

Anyone know what the issue is?

That was a fantastic suggestion. I hadn’t thought of that. Unfortunately, I’m not using any keyboard/mouse software such as Intellipoint, so it’s gotta be something else.

Keep ’em coming!

Yes. I always try to avoid installing anything extra that could hinder performance.

I’ve seen this type of inexplicable performance oddity occur from video card driver bugs, fixed when reverting to prior or subsequent driver versions (especially when "marching ants" selections are involved.) You can try disabling or scaling-back Hardware Acceleration temporarily to see if it’s a video driver issue. (Display Properties/Settings/Advanced/Trouble Shoot – in XP – not sure about Vista)

Mark,

Have an instance of Task Manager (Processes tab) open while you experience this.

Click the Processor column to toggle the thing that claims processor resources most to the top of the list.

Check whether it’s PS or somthing else that does this.

Oksy. Did that (taskmgr), and it’s Photoshop that’s pegging the CPUs. Photoshop goes up to 90+% of the system when the tool is selected. Once I change tools, it drops back down.

Sometimes PS can show this behaviour if the default printer is a network printer that’s not found.

I do have an old network printer that i cannot remove. it’s not the default however. when i try to remove it, it says "printer cannot be removed. make sure that you have typed the name correctly, and that the printer is connected to network." well that’s just silly. you cannot remove it because it’s removed. i bet that took a lot of planning! :o)
