Open Bench Logic Sniffer / LogicSniffer client not working as expected
While trying to figure out how things work, I managed to attempt a capture (nothing useful), but it appeared to be working (I saw a tiny little blip). Then I somehow managed to get myself stuck in this mode where I can't see the diagram, all of the tools menu items are gray except for serial console, the measurement tab is disabled, captures never end and I can't cancel them once started.

I've tried resetting the OB and relaunched the client, but nothing changes.

How do I get myself out of this situation?

Open Bench Logic Sniffer / Can't load FPGA on new OLS v1.04
My first problem was that I didn't get a USB port when I connected it to my MBP (Mavericks). So I loaded all the software to a Windows VM and connected it there. I really want to use it from the MBP, so I decided to update the PIC and FPGA.

So the first thing that happens is that the PIC update has intermittent success -- very flaky. When I try to update the PIC from ols_upgrader, all I get is timeout errors. It's successful with ols_winloader, but only about %50 of the time.

I can't update the FPGA at all -- from neither ols_upgrader nor ols_winloader. ols_upgrader keeps telling me it can't write to flash ROM. ols_winloader says it can't erase the flash ROM.

The other thing that's flaky is that I sometimes have a hard time getting it into bootloader mode (by shorting the two pins -- not using the ols_upgrader tools).

I've tried different USB cables and reinstalled drivers, and keep getting the same results. It's probably worth mentioning that this is one of the OLS's with the WinBond flash.

Does this sound like a bad OLS? Or are there other things that could cause the kinds of failures I'm seeing?
