OK,

I am going to do my best to explain this
windows 10 RunJS Version 3.0.3

1. say I have 3 tabs open do what I needed and I close the program
2. the next day I open the program my three tabs are there but I do not need them anymore so I open a new tab and then close those 3 so that now I only have my new tab open
3. Now I cannot type in that tab I have a flashing cursor but LOL did my keyboard just break
4. pause bang head on desk
5. Ok so click new tab and and type in the tab all is good
6. Go back to first tab now I can type in it as normal maybe banging head on desk fixed it
7. So I close the second open tab cause the first one is working
8. so left with one tab open and cannot type in it again still have flash cursor when click in tab

So with all that said I can repeat this process a few times with new tabs and open and closing the software a few times with same results....... BUT it does seem that when I duplicate this issue I can finally get the tab to respond to the keyboard if I then click somewhere in the output console then I can type in the tab normal again

I hope my explanation is clear enough
