SQL Window hangs on right click

[riz]

I am using version 6.0.3.893 of pl/sql developer. Lately, occasionaly developer hangs when right click to describe an object. At other times,clicking in the grid hangs the developer. I have been on version 6 for sometime now. Anybody else experiencing the same issue?
any fixes?

This indicates a performance problem of the Oracle Dictionary views. When describing an object, certain Dictionary views are queried.

When accessing a result set for the first time, this also happens. To prevent this, you can go to Tools > Preferences > SQL Window and disable the "Show dictionary info in result grid" preference.
