Every time I reopend the Find and Replace dialog box (CTRL+H) in Microsoft Visual Studio 2010,  the width of the dialog box grew by several pixels. I was looking through various settings in Visual Studio, however, I haven’t thought of a bug in Visual Studio at all.

Finally, Alex Zeitler pointed me to a hotfix  for this issue. The Knowledge Base entry KB2268081 explains the issue in details. The issue affects the following products:

• Microsoft Visual Studio 2010 Shell (Integrated)
• Microsoft Visual Studio 2010 Shell (Isolated)
• Microsoft Visual Studio 2010 Ultimate
• Microsoft Visual Studio 2010 Professional

In case you use the Find and Replace dialog quite often, you might download and install the hotfix from the connect site.
