Methods | Selected Classes or Methods, Filter outgoing calls - if displayed as a lightweight popup (fits the main window area), can be edited. If a heavyweight popup is used (main window is small), the text component doesn't show cursor and its text cannot be changed.
Experienced on Windows and Linux. Mac OS X is always broken as the popups are always heavyweight on that platform.
Fixed by http://hg.netbeans.org/profiler-main/rev/c6623668e259.
Integrated into 'main-silver', will be available in build *201612080001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: Bugfix #269240 - reimplemented profiler popups to always use a heavyweight window
- should also resolve problems with closing the popup when opening a modal dialog from it
- likely introduces new problems (strange behavior on Linux, overlapping value tooltips etc.)
