Hello,

When I hit the button "attach to tangle" the wallet window turns black after a short while.
I already had the same problem with the light wallet 2.5.4 and the problem still persits with the updated version. I do indeed have a Intel HD graphics 4000 card but my drivers are up to date. Anyone any idea what's the problem here?

There is 2.5.6 already, try that one.

Unfortunately the problem still persists with version 2.5.6...

You can try uninstall it and delete everything from your users AppData/Local folder, after that install the 2.5.6 version maybe it helps.
Otherwise ask devs on slack
