The problem doesn't show up on non-386BSD operating systems; because of "less strict" memory checks. Basically, the code in the server which drew lines would overwrite the end of an array. There is a new version of 1.3, 1.3u1 (update 1) which corrects the problem. Also, there is a problem with line drawing in the speedup mode of the ET4000 code; the problem only occurs when your virtual width is not 1024. The update removes the particular speedup which causes the difficulties. All these items were revealed in the newsgroup which handles XFree86 problems, and, I believe an announcement of this was posted here earlier - so, for more details you may want to look there. - Dave Rivers - (rivers@ponds.uucp (home)) (sastdr@unx.sas.com (work)) -- UPDATE ALL INFORMATION AND POD INTO COSMOS - Federal Express
