This morning I made few test to reproduce the error.
case 1 : starting windows and checking my usual website (opening Azureus to
download some stuff), then starting sip communicator. --> Error
case 2 : rebooting computer and using the other run.bat file : nothing
happens. Using the standard run.bat --> Error
case 3 : rebooting computer and starting immediately Sip. --> No error
case 4 : rebooting computer, checking the sames website, opening Azureus and
finally starting Sip. --> No error
The only difference between the cases 1 and 4 is updating my antivirus
database. I will check this tomorrow morning
During theses tests, I've found two others error some problem with the video
: cf the screenshot for the first one.
And for the second one, it appears when I wanted to reinstall Sip. The
installer told me that the file : jmvfw.dll is still used (and consequently
not removed by the uninstaller).
