Update to my rant wrt mplabx before: - I apologize, I was somewhat irate after several wasted hours, also for ot= her reasons. - The mplabx works fine once it is restarted 2 times or so assuming a fresh jdk installation. Apparently some things are not set up right from 1st ti= me. In case of trouble one should exit the login session and log back on afte= r reinstalling/upgrading java, then try to start mplabx again. - Online connection (internet) is absolutely necessary when the mplabx star= ts up the 1st few times, some updates appear to happen on the fly when this occurs. After that the machine can be used offline or online. - For disasm and single stepping to work, it is necessary to select the relevant 'save intermediate files' option in the Loading section of the project properties. The F7 step keyboard shortcut appears after the above updates occur in the background, and once the project is compiled with th= e intermediate files option enabled. - The disappearing windows and so on problems I was seeing were apparently caused by the ide cleaning up the temp files, such as disasm, while they were in use, causing java exceptions. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
