I'm currently locked out of my wallet due to it freezing when opening a wallet which is very small and has done very few transactions. ive reinstalled twice now and its still broken.
I have a gaming computer which runs the latest games so it should be able to run this small application. i havent got any other computer to test on.
What version you are using right now ? because there was various GUI improvments on the latest versions of Electrum if you look at the Github
