A couple more observations to help nail the problem. It seems one issue has to do with HHTP Exceptions not being handled properly. Zooming in to one WMS layers (massgis:GISDATA.IMG_COQ2005 at http://giswebservices.massgis.state.ma.us/geoserver/wms) I managed to go down to the level I wanted a few times, but most of the time zooming in would trigger a timeout (> 120 s, can't remember exact message), then a HTTP Exception dialog would pop, then the "QGIS has encountered an error" death window. I meant to test with uDIG, but it ran for 20 minutes without rendering an image, but at least I could see the little green progress bar showing it was working. I stopped it, so I'll never know if it would have crashed in the end or if it was standard Java waiting times ;-) A (related ?) point : I experienced problems in overlaying vector and raster data. My first try was NASA global_mosaic and Tiger roads data (from the MassGIS WMS server). Roads were off. Then I figured I'd try MassGIS raster data (mentioned at the top of this message) and I had that offset too. Ticking the project on the fly option in the preferences didn't seem to do much. Finally, I wonder if it would be possible to cache the GetCapabilities response to a local file so the list of available layers pops up directly after one adds a WMS layer (in the case a layer was added beforehand, of course). In the case of the MassGIS WMS server it's close to 1,5 MB of data upon every connexion. On a slow connection, that may be a real issue.
