Hm, I'm afraid that Rom doesn't test the BOINC client is not very much on Win9x/ME. Which version prcisely did you download? And did it all work with 4.19? I'm running a Win98SE machine @home and have never been satisfied with clients newer than 4.19. It's a somewhat slow machine (Celeron 600) nowadays and the BOINC Manager itself takes too much CPU time from crunching.
