Hi. Running licensed VMs w/ Arduino IDE 1.5.8, compiling to Due, on both a workstation and laptop. Both the workstation and laptop are roughly equivalent: Win7 Pro 64-bit, 8GB, SSD drive.

On the workstation, the build takes about 1 sec. and everything is fast.

On the laptop the build takes about 3 sec. - no big deal. But once the build is complete the VM IDE hangs for 15-20 seconds (after the "Binary Sketch Size..." message.) Process monitor shows Studio running at 25% CPU while that hang happens, so it's doing something.

I've checked all the network-ish things and tried disabling the antivirus, and verified the VM/VS settings/properties to be the same on both.

I'm wondering if you might have any ideas where to look further.

Verbose messages are on. There is nothing displayed in the Micro Build window after the "Binary Sketch Size..." message.

Studio just hangs after that message for about 15-20 seconds. No editing, no menu dropdowns, nothing. (I should note that everything works OK, it's just that that damn hang is seriously crimping my style.)

If I run process monitor on the workstation, AtmelStudio runs up to about 25% CPU (quad-core) during the build, but then drops right back down to 0% when it's done. Build time on the workstation shows about 0.9 to 1.1 seconds.

On the laptop, it seems to only run about 5-10% CPU during the build process, but then CPU goes up to 25% and stays high until about 15-20 seconds AFTER that final build message. Build time shows 3.17 seconds on the sketch size message.

Kind of weird.

Upload after build is maybe a bit slower, but nothing I care about. That could be USB ports or who-knows-what.

Arduino IDE is 1.5.8 on both. Atmel Studio shows 6.2.1502 SP1 on both.

Yes, sorry if I wasn't clear. Just F7 or "Build"..."Build Solution"

Thanks for the update. I expect that restarting the ide was what was required because the other items are unconnected to the build process.

Appreciate the update thanks again
