Ever since Visual Studio 2010 was released I’ve noticed that the find/replace dialog was constantly expanding. After multiple openings and closings I needed to resize it to make it usable again. Apparently I wasn’t the only one that noticed since it was the one of top reported issues at Microsoft Connect.
If this problem is bothering you as much as it was me there’s good news. A patch is available to resolve the issue. I installed it over the weekend and haven’t seen the problem since.
