Thanks to eried, to neophob (http://neophob.com/2011/05/serial-library-rxtx-v2-2pre5/) and to the guys and girls working on RXTX (the piece of software we use to make the pc communicate with our boards) I've managed to fix the "tools" menu delay issue.
I need someone volunteering and testing the fix. Instructions below:
Attached you can find a .zip which contains 2 files. You have to overwrite the existing ones with the ones attached. BEFORE you do so, back them up: copy them somewhere else, so you can restore them if bad things happen.
One file is "RXTXComm.jar": it is a multiplatform file, everyone of you has it under folder "lib" in the folder where you have installed your arduino ide.
The other file is specific to your operating system: I've managed to make the linux 32 and 64 bit and windows versions. Mac versions will soon follow. If you have a 32bit or 64bit linux, copy file librxtxSerial.so from folder linux32 or linux64 into folder "lib" (right next RXTXComm.jar) If you have windows, copy file windows/rxtxSerial.dll into the folder where you have installed your arduino ide (right next arduino.exe)
Run the ide and report back: is everything running as usual? If you were experiencing the tools menu delay: has it disappeared?
Thank you in advance
