[galaxy-dev] Strange/Missing HTML code in history pane

Hello, Some of my galaxy users are seeing histories without being able to "expand" a dataset (see attached image). It seems some of the javascript/html code is somehow missing or not executed. The attached image is from Google Chrom on Windows XP. The user tried Firefox (on windows) and everything worked fine. I tried Google Chrom on Linux and it work fine, So reproducing it is a bit hard - but it does happen more than once. Any ideas on how to pin-point the problem ? Is it network related (the connection dropped before completion) ? thanks, -gordon
