Just an update. I posted this in another thread
" Getting severe performance issues with my install, especially screen refreshes and reading the database explorer also getting not responding errors it I try and do anything on screen. The monitoring in the background seems to be working fine.. "
I believe the cause was the map I was using. Sometime ago I took a default map changed the position a little and saved it as a map to re use. And re used this as my default It seems my performance issues occured whilst I was using this custom created map. When I go back to one of the default maps my screen refresh performance is back to acceptable levels.
Also my system continually crashed. I have found this coinsided with my Kaspersky AV software scanning the system. I have excluded the Airnav directories from being scannned and this seems to have resloved that problem. Will just have to do a manual scan of the excluded dirs every now and then.
Hope this is of benefit to you all.
