Also, if I download messages, then click away from the inbox to another folder before opening those new messages, when I click back on the inbox, they are no longer visible.
The glitch also has removed all messages from my inbox back to Feb. 5, 2011. Older messages remain.
The program also crashes frequently.
Note: This problem began occurring a few weeks ago when I was experiencing many system crashes and BSOD. This was traced to a faulty memory module which has since been replaced. However, the problem with email client remains.
Malwarebytes scan is clean, as was full Kaspersky scan (although I have removed Kaspersky) and Windows Security Essentials scan.
Thanks for any suggestions you can offer.
