Using the Data Merge Manager I can no longer resize the floating window? Have the same problem with beta and non beta. Every other window works as expected. No other program I use has the issue either. As shown in the images I can resize Publisher but when opening Data Merge Manager it takes up the whole screen with no control over it. Main monitor is 4k and normally I could drop the floating window onto the HD monitor but now it remains fixed at 4k size. Running windows 10 os build 19043.1081
