We are currently working in a mixed environment (Notes 4.6 and R5). Randomly on clients pc's (usually Win95) when selecting an attachment option, their pc locks up, no error message. The only answer is to reboot. Usually deleting temp files (both c:\temp and c:\windows\temp) and netscape cache clears up the problem. However, I have some clients where the problem keeps reoccurring. Has anyone seen this?
