I’m a Mac user so I can offer only generic advice:
Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by pressing command-alt-shift/ctrl-alt-shift while starting Photoshop until the appropriate dialog appears after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)
And a Forum search for »_MVM_.tmp« would point you to threads like this
Thanks c.pfaffenbichler for reply.
I have done ctrl-shift-alt while starting PS and reset all preferences.
But still it is not working. As if liquify and other filters have lost their functioning.
I suspect the MVM files are Mondo Virtual Memory files used by some filter plugins. If they are not being deleted you may be getting abnormal plugin filter exits. How much free disk space do you have on your D: and E: drives? If there is insufficient hard drive space for the filter to work properly, you could get this type of behavior.
On D: and E: I have 11Gb and 8 Gb free respectively. Do I need to clean these drive to avail more space?
The reason for my surprise is all PS filters were functioning before properly. Now they are none of any use.
Please guide. And thanks for your reply and time.
Can you make a list of the filters that fail and the filters (if any) that still work? We can then compare how the filters are implemented in Photoshop to see if we can find a common trait. What changed just before the filters stopped working? Was there any new software/hardware changed, installed or updated?
