Fritzing crashes under Lion when modifying a resistor value

mrobin604 4 years ago

Hi Fritzing folks,

I am just starting to use your software, and I found a crash when I modify a resistor value by entering it manually with the keyboard. To produce the crash, I open the application, drag a resistor onto the work area, then select the resistance value and type in some number, and hit return. It crashes 100% of the time if I do that.

Here's the call stack for the thread that crashes. I didn't put the entire log, if you need more info I am happy to provide it. I am using the current version of Fritzing, downloaded today.

Hi Mrobin,

Sorry for the crash.  This has been fixed and will be shipped with the next release. In the meantime, there are several possible workarounds:

  • go back to version 0.6.2
  • build fritzing from the latest source (something of an effort)
  • save the sketch and change the resistance in the fz file (which is just an xml file)
