Report Explorer not opening up

Hi,
Ran a few backtests and wanted to see more detail on previous ones.
Click on Report Explorer, hourglass comes on - then nothing but blank screen.
Checked Amibroker C drive and all of them are there.
Looked at settings, etc and nothing seemed odd.
Help, please

So is it opening or not? Because in one sentence you write that is is "not opening" and in the second sentence you write that "then nothing but blank screen". So it is opening with blank screen?

Unfortunately your question isn't clear enough and does not provide all necessary details to give you an answer. Please follow this advice: How to ask a good question

Maybe you are using some strange antivirus that destroys normal operation of Windows: AmiBroker Knowledge Base » Third party software “black list”

Try double clicking on ReportEx.exe

It produces a blank screen when I click on Report Explorer before running new backtest. There is no drop-down list of previous backtests.
After running new backtest, the hourglass appears and results of latest backtest on screen.
If I double click on Report Explorer, all I get is the latest backtest result.
I use Firefox and no added anti-virus software - just good old-fashioned common sense. No banks, etc have been in touch to tell me I've been cleaned out. I checked to make sure.

Please send a screenshot of Report Explorer window.

Tomasz, I think I've got a bigger problem.
The print screen did not work. Connected usb keyboard and mouse instead of my wireless ones and still did not work.
Maybe best to leave this till I figure out what's going on with my PC.
Thank you for your help.
