Issue I115 [70,logic,med,resolved] SIMION may crash on startup if another SIMION7 or SIMION8 running and 1000 GUI*.TMP files exist in C:\FILES.GUI Prior to 8.0.3-TEST9 and 7.0.5, SIMION could crash on startup if all 1000 GUI*.TMP files exist (no more unused file names available). SIMION would crash on attempting to write to an empty file handle. A workaround was to delete some or all of the C:\FILES.GUI\GUI*.TMP files. As of 8.0.3-TEST9 and 7.0.5, SIMION gracefully skips writing to a GUI*.TMP file if no more names exist. Affects 8.0.x and 7.0.x versions. Resolved in 8.0.3-TEST9 and 7.0.5.
