So I have tried this on three Domino 8.5.2FP2 servers (one Win2k8R2 64bit, two Win2k3 32bit) and on one 8.5.2FP1 (Win2k8R2 64bit).
I have the ExtLib installed fine, and I've copied the Dojo-1.5.0 stuff to the JS folder, copied the IBM folder and removed the *.gz files from it.
Everything works dandy in Chrome, but in IE7 & 8 file upload control button doesn't work - it seems to be text inside a table cell.
Mr. Google tells me that there are some isues with IE7+, Dojo and the latest Flash releases, but I don't see any solutions.
If anyone has any idears on what I'm doing wrong, I'd appreciate knowing.... (thanks!)
