Hi Dave, I did get it working by deleting a few files I found under \Users\Phil.jNetMap. I'm pretty sure it was related to saving maps on a network drive & having them remembered, as I have another java based app that gets upset is I try & save it's data outside \users\Phil etc.... I would like to try the latest 0.5.5, but have not been able to find it as your dropbox link on this page, http://www.rakudave.ch/jnetmap/download , gives me an error message, "There was a problem completing this request"...
Seem to be suffering a similar situation. I launch jNetmap & it appears on the task bar, but no GUI is active. All was fine last week. Only changes were maps were on a network drive. (E:\jNetmap), that was that way for several days. Thing that seemed to break it was me setting preferences to load perviously used files. Tried all avenues of uninstall/reinstall, including Java reinstall & still no GUI. Also unsure where all settings are stored to reove completely. Win7 64 bit, jNetmap 0.5.4. Please...
