Created attachment 100132 [details] Patch to fix invalid pointer dereference under win2000 On windows 2000 there is a crash when attempting to render scrollbars, this occurs because the code allocated a theme engine and then trys to get a theme handle from the engine without first checking if the engine is valid. On windows 2000 there is no theme engine so this fails. It is possible this might affect some more modern platforms as well, e.g. Windows XP "lite" modes where people have ripped part of the shell out, or maybe some of the server range windows under certain circumstances, but either way it is better to correct this. Simple patch attached.
