ME shell + explorer probably do decrease stability, because it is possible that certain ME API functions may not be properly supported by 98SE.That's the other reason why I keep option 3 separate. READ1ST.TXT, under the "EXTREMELY IMPORTANT" + "98SE2ME.PIF COMPLETE GUIDE" [the "* Option 3:" paragraph] chapters, contains a little hint: CAUTION: WinME files installed by option 3 may change/lose Win98 SE interface functionality! You may also want to ask Tihiy, he's the author of Revolutions Pack, based on API functions from ME + XP. UPDATED 6-19-2005: I just updated READ1ST.TXT: READ1ST.TXT to include this statement: CAUTION: WinME files installed by option 3 may change and/or lose Win98 SE interface functionality, stability and/or performance!under the "EXTREMELY IMPORTANT" + "98SE2ME.PIF COMPLETE GUIDE" [under the "* Option 3:" paragraph] chapters. Hope this helps. <{POST_SNAPBACK}> MDGx, How do you back out of option 3-- I reinstalled explorer+shell32+comdlg32 and ran your ZIP files -- the one "To fix the Start button issue" W98SE.BAT(W98SE.INF) and this made START button work except SEARCH, but MY COMPUTER default is now -SEARCH- and FOLDER when you click are the default OPEN HERE COMMAND. How do you change the default for MY COMPUTER and FOLDERS--right click and you can select OPEN and it works, but can't set as default--this is not set in register anywhere and FILE TYPES can't set it? Does this have anything to do with DESK.CPL? Versions for the explorer,shell32 and comdlg reinstalled from 98CD with SFC. Any HELP here for this?
