Sd card applications are missing... Plz help

[supanatuwral]

This problem happens with multiple roms.....I have used cm6, omj, and fresh roms and had many problems moving apps to the SD card. The problem comes after not using my phone or after a reboot. The problems range from the apps disappearing or not being usable while still being installed. I have had the market stop working and apps not being installable, even the ones on my sd card. Without my nandroid backups I think my phone would be unusable. I have done as much as I can to try and fix this problem, even log in and out of Google talk. I have decided to not install any apps to the SD until this one gets figured out by the android pros here or at xda. I know there are threads talking about this, but I don't see a permanent solution.
