Empty UI Gestures Collector dialog is repeatedly opened when the computer is not connected to network. It even causes deadlocks when running automated tests. You should somehow handle state when it cannot connect to desired location. IMO, it should ignore it silently in such case. To reproduce: - unplug your network cable - start IDE - cause an Exception in IDE (e.g. in build 200701091900 open Tools|Options and click Editor category) - now you can see empty UI Gestures dialog and if you click Cancel button it appears again. Also SocketException is printed out to console.

Works for me on my linux, maybe duplicated of issue 91999. Please check tomorrow and possibly tell me on which platform it misbehaves, I guess the actual exception thrown on bad connection is different on different OSes/JDKs and I need to catch all variants...
Now it works for me on windows, but while testing it throws NoRouteToHostException on Linux 2.4.21-37.EL, JDK1.6.0-rc-b95, build 200701101900: WARNING [org.netbeans.modules.uihandler.Installer]: http://logger.netbeans.org/nonav/welcome/error.html java.net.NoRouteToHostException: No route to host at java.net.PlainSocketImpl.socketConnect(Native Method) http://ffjqa.czech/automatedtests/xtest/netbeans_dev/200701101900/qa-functional_validation/qa-linux-perf_1/testrun_070111-022427/logs/web_jsf_qa-functional.log
Ok, special handling for NoRouteToHostException: /shared/data/ccvs/repository/logger/uihandler/src/org/netbeans/modules/uihandler/Installer.java,v <-- Installer.java new revision: 1.41; previous revision: 1.40
Seems to be fixed at all possible configurations. Thanks.
