There is an issue with VS 2010 that shows an incorrect message:

"Insufficient available memory to meet the expected demands of an operation at this time, possibly due to virtual address space fragmentation. Please try again later."

When you try to Cut or Copy code.

If you run with this issue there is a release of a patch that can be downloaded in the following link:

All you need to do is download and install it.

Note: In case of a real memory problem this patch will do nothing, it will only solve the problem of false memory errors.

Have Fun!!!
