I am experiencing the same problem with every CS4 PhotoShop tool I use -- HELP! PhotoShop has become completely unusable.
different instructions--same result [5th through 8th digit changes in error message]
the instruction at "0x20322c9b referenced memory at "0x00000028". The memory could not be "read".
the instruction at "0x206f2c9b referenced memory at "0x00000028". The memory could not be "read".
the instruction at "0x207e2c9b referenced memory at "0x00000028". The memory could not be "read".
Pretty much standard advice applies...
Things to try:
1. Try disabling OpenGL drawing (closing and reopening Photoshop afterward to test), and update your video drivers from the web site of the maker of your video card.
2. Reset Photoshop preferences to defaults by pressing and holding Control-Shift-Alt immediately after starting Photoshop, then confirming the deletion.
3. Ferret out any non-standard fonts that may be corrupted or incompatible Photoshop.
4. Check your system for malware.
5. Check your Windows system integrity (e.g., SFC /VERIFYONLY and SFC /SCANNOW commands).
6. Reinstall Photoshop and make sure it's up to the latest patch level.
When one encounters Memory Address issues, it is often related to a program/process that is not accurately reporting its memory address use, or is telling the OS that it has released addresses, when they have not been released.
The first troubleshooting task that I would undertake would be to pour over Event Viewer, looking for error, or warning messages at that time. Then, I would follow every link offered, to see if I could track down what was causing the memory address issue.
