Trouble with Rename Controls

When I drag a control to the page, eg, a Label , the IDE automatically created a Label on the page and in the property named it with "Label1", then when I try to change the name "Label1" and press enter, I always poped up this error message

"Property value is not valid. Details: Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

So I cannot change the controlID. The same as when I create other controls.

Is this a common problem?

I haven't see such problem before. Have you encountered other memory issues?

Sometimes after I restarted my computer, there would be no problem.

So I think this is just my very own case related to the underlying bugs in my computer.

Thanks!
