Hi, what is your browser and which version ? Can you hit the F12 key and see if you have any errors in the browser's console ?

Do you use the AsemonReportSRV package on windows or do you use your own Apache install ?
In that case what is the PHP version ?

You can check in the Apache error log if you get some messages (on windows : apache\logs\error.log)

I have used this version for RS monitoring recently and had not these problems

Best regards
JPM
