IDE 1.0.4 Tools loading problem.

After installing version 1.0.4 IDE loading a sketch can take up to 10 seconds.
Also acessing theTools menu takes some time to show.
Starting the terminal has the same problem.

Is this a bug in the IDE or is there something wrong with my system.


It is because a bluetooth dongle/another serial device. You have 3 options:

  1. Disconnect other dongles/etc

  2. [MOD] Arduino Enhanced Release 1.0.5 for Windows (installer, drivers, etc) +SRC - Libraries - Arduino Forum
