While dimensioning - autocad crashes

[Anonymous]

I have been dimensioning a string of dimensions and I will continue to dimension to a separate string of dimensions and autocad crashes. On recovery it will change my default dimension style to an override, that creates a font twice the size of my Standard dim style.

It produces the following error message: Unhandled Access Violation Reading 0x0006 Exception at 64556354h

I am using dynamic blocks that I have created with the stretch parameter. And it seems if I explode the block, it will allow me to continue to dimension. But this is not a fix... only temporarily. so far this morning 10 times, my computer has been down more than I have been able to get work done.

If anyone has a solution, or and idea what may be going on please let me know.

have you ever received any help with this problem? i've been inconvenienced with this problem while using autocad mep 2011.

my problem happens during dimensioning using linear, continue, and aligned. i can get in a few dimensions, with a bit of a lag between a few seconds to almost a minute, and then it crashes leaving this popup message:

"FATAL ERROR: Cannot write to undo file (probably disk full)"

the program allows me to save a recover file of the drawing, then shuts down completely. at the same time, another popup opens asking you to fill out information on what exactly you were doing when the system crashed. well, after about a hundred times i quit filling that space out.
