X Error of failed request: BadAccess

Hi, Can anyone please shed some light onto where I can start sorting out this error message:? X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 145 (MIT-SHM) Minor opcode of failed request: 3 (X_ShmPutImage) Serial number of failed request: 194 Current serial number in output stream: 195 I am using a vector and raster graphics product and are busy putting together a new PC with SuSE 9.1 Both parts of this SW worked on SuSE SLE8 but, on SuSE 9.1 the raster side (I am trying to display a tiff image within this package) bombs with the above X error. Any ideas as to where I can start hacking this problem would be appreciated. TIA, Zoltan.
