Hello,
We have this problem.
After select Check-in of a file in our database a new windows appear.
In this windows you can select the file for the check in drugging it on the screen or selecting "Browse..." button.
In all case, after the selection or when you drop the file on the windows, the windows automatically close.
I've made some check, it doesn't dipend by Java version, IExplorer is the same for all version 9 32 Bit.
How I can solve?
Please help us if you have had the same issue.
Thanks
