Access Violation on terrain raise/lower

[Nobby]

Hi all,

It's been a while since my last visit but now one of my friends has a problem with CentrED 6.1.

When he tries to elevate or lower a terrain tile the app crashes with a access violation popup. Now we've scanned most of the topics here related to the problem and have ruled out the "old driver" thing. Even more interesting is the fact, that it's OK when the display is set to "flat" mode.... No other process is using the mapfiles. Any ideas ?
