I am unable to start Gaussview 5 on my mac. I have the wine version 1.3.21. I get the following output: fixme:imm:ImmReleaseContext (0x10040, 0x18f308): stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32fa48 - stub fixme:advapi:GetEffectiveRightsFromAclW 0x19ea1c 0x3a297aa4 0x32f8f8 - stub err:ole:RevokeDragDrop invalid hwnd 0x0 err:ole:RevokeDragDrop invalid hwnd 0x0 err:ole:RevokeDragDrop invalid hwnd 0x0 err:ole:RevokeDragDrop invalid hwnd 0x0 Then the program hangs Thanks, Dan
