In the past 2 weeks, I have begun to have intermittent crashes while using Eudora Pro 5.1, with Type 1 or Type 2 Errors. Usually occurs while mail is being downloaded from mail server. After the crash, when I check About This MacIntosh under Apple Menu, the size of the of the MacOS has jumped from usual 20-22 MB to an apparent 80 to 136 MB. The memory leak is not occurring with other programs, even Microsoft Word, the more usual culprit. Eudora 5.1 had been working fine previously. I have not installed any new or updated software (other than Shockwave Flash 6.0 r79). Any suggestions as to cause of problem or to fixes (other than reinstalling Eudora)?
PowerMac 7200/90, OS 8.6, 48 MB RAM with Ramdoubler installed.
