Because it worked better after I deleted it. My window positions are coded in the batch file and you can also use Windows to save them. My windows stay nearly minimized at the bottom of my screen just above my task bar. I run my normal office apps partially minimized so that I can always glance down and see what freq the scanner has stopped on, etc.. I run one dongle for P25 trunked freq and that has many agencies that use the one control frequency. Standard advice is to not delete the bin file but someone suggested it when my system had issues. One advantage of deleting it is that it returns the system to a know stable state. May not be best solution for everyone. Works for my configuration. Text sizes have been ok also...
For FMP24/DSD+ scans, I run them from their own folder.
The advantages are:
-They are easily transferable should I need to use other equipment.
-There are no conflicts even when I run several at the same time. I provide them with individual TCP addresses.
-I do not want to cludge, compromise or delete key configuration files to make it work.
-Each is easily customizable or/and easy to troubleshoot to fit need.
It provides me with a smooth running system where issues can be isolated if they arise.
That is just me though and my system management background.
