#1 sometimes I get missed flippers or stuck flippers, this could simply be a windows software problem but still trying to track it down.
That's probably a software problem on the PC side; it's not the sort of thing that happens on the device side.
I've seen that happen in VP with ordinary keyboard input (which is why I'm pretty sure it's a PC-side issue). I'm not sure exactly what the cause is, but it seems like the times I've seen it correlated to CPU overload, and in some cases scripting bugs. If you're seeing it in specific tables, it could be something in the scripts in those tables, or it could just be that those tables are causing especially high CPU usage. If it's across all tables uniformly, you might be able to improve things with some performance optimization (some ideas here: http://mjrnet.org/pi...?sid=optimizing).
Or it could be some other issue entirely - my notion that it's performance-related is vague at best. Maybe ask in the VP forums to see if anyone has any idea what causes it.
#2 sometimes after I shutdown the windows machine the pinscape controller doesn't come back up after powering the machine back on resulting in two short red flashes and continues until shutting down the system, a windows restart will not get it out of this mode. I thought I fixed this by disabling fast startup in windows but it has come back again.
That's a USB issue - it's some kind of incompatibility between the KL25Z's USB and your PC's USB host. Those were more common with earlier versions of the firmware, much less so now, but it's hard to eradicate them completely because they keep coming up with new USB chip sets on the host side with new peculiarities.
This type of behavior is due to the interaction between the USB host and device hardware, so there are two things that can often clear it up:
1. If your PC has a mix of USB 2 and USB 3 ports, try moving it to the other type from whatever you're using now. The two types will use different hardware chip sets and completely separate stacks of Windows device drivers, so it's rather like plugging it in to a new computer.
2. Add a USB hub between the PC and the device. The interactions are between the directly connected hardware endpoints, so adding a hub changes the hardware that's talking to the KL25Z side.
I am on firmware 2016-06-14-1938 running windows 10 version 1511. Do you think updating the firmware will make issues #1 and #2 more stable?
It probably won't affect #1, because I don't think that has anything to do with the KL25Z. It might help with #2, but it doesn't look like there are any significant USB changes in the revision history after that point. I fixed lots of USB bugs in the mbed libraries early on, but it looks like they're all well before June 2016.
