We just released version 1.9.4, with binaries for mac & windows.
This should fix the various bugs reported since 1.9 was launched.
Just download portable version 1.9.4 on Win7-x64
I got a small problem when I try to change the field "Display zeros". I set it to "8", and click ok. Right after, all my balance is shown with 8 digits after the decimal point.
However, upon closing and restarting Electrum, it turns back to the original setting (no digit after decimal).
Could someone please check if they can replicate the same problem?
Thanks.
