Zimbra Desktop Startup Issue

[jws3154]

I have scanned thru several of the most recent pages and did not find a issue similar to mine. Please excuse if this has been covered before

I am running Win Vista Home Premium ver 6. I have looked for a ver # for ZD but cannot find one.

After many months of trouble free use, Zimbra Desktop now will not startup on first try. It gets to the screen with the three logos - airplane, etc - and hangs there. The logos continue to rotate, but it will not proceed past that point. If I close the window and restart, it will fully load on the second attempt. However, I have to double click on the icon 7-8 times to get it to load. On the first 6-7 attempts, the cursor will change to the loading symbol briefly then return to the standard cursor.

Thanks for any assistance or advice.
