I've been having some random freezes in Pegasus Prime. The music or ambient sound continues to play, but the game freezes and i can no longer see my cursor or move. The game menu cannot be accessed either and the only way out is to force terminate the program.

This happens randomly, but usually when I try to enter the room where the oxygen dispenser is in the Mars Section right after you leave the tunnel pod. I open the door above the stairs, and the game immediately freezes.

It can happen on other occasions too, such as using video log in Sinclair's office.

Anyone got any idea how to fix this?

If the audio is still running in this frozen state, then you may be experiencing the "num-lock-occupies-the-same-location-as-the-clear-key-to-access-the-inventory-panel-and-locks-up-my-video" issue on some keyboard configurations. Try pressing this key again to see if this unfreezes the game. There are more details about this on the Journeyman Project web support page. http://thejourneymanproject.com/presto/journeymanprime/support.html

Cool, thanks. Will try. :)
