I open LM, I get my email, I exit LM, I open LM, I get my email, I exit LM.....ok

I open LM, I get my email, I send an email, I exit LM, I try to open LM, it does not open (usually say not connected), I go to Task Manager and end LM, I open LM and every thing is OK.

this happens every time, I send an email from LM.
