Upgraded Coldfusion from 9.0 to 9.0.1 - new cfgrid problems in Firefox

After running into problems with auto-suggest stripping off leading zeroes, I took the plunge and updated my dev copy of CF to 9.0.1, including the cumulative hot-fix. Now I see a new problem.

Every one of my existing cfgrids is now displaying incorrectly in Firefox 6.0.2. The .x-panel, .x-panel-bwrap, .x-panel-body classes have a computed width of 12px,开发者_JAVA百科 and are basically unviewable. I find that if I insert a css rule on those classes like so:

.x-panel, .x-panel-bwrap, .x-panel-body { width: 100% !important; }

the grids are again viewable. I did clear the browser cache to make sure it was importing the correct files.

IE8 and Chrome both seem to be unaffected.

OK, Peter, why not? My workaround, as posted in my question, is to add the following css rule:

.x-panel, .x-panel-bwrap, .x-panel-body { width: 100% !important; }
