Problems seeing pictures in arcive and my alerts

Mi pictures in the arcive is not showing up as usual.
It takes a looong time to get them, sometimes they show but mostly there is either a “red cross” or just a blank frame.
Sometimes I can open it by the cross and perss"show picture" but mostly not.
I have had the problem for about 3 weeks.
I wrote to support, no answer yet, but this may not be a vera problem.
Anyone else tryed this ?
I am on vista, explorer 9 (have tryed firefox too) and ui5.
Hints are welcome !
