Serial monitor stick @ bottom banner can,t be used

[ilioSS1]

Hi,
Arduini github send me to this forum about this issue.
I can,t use my serial monitor?
using 1.8.13 so I updated to 1,8.19 still no usable serial monitor.
From the early beginning I was able to use my serial monitor without any problem.
If I want to use the monitor I click on serial monitor. Normaly it apeared on my screen where I write my script . Now the serial monitor is sticked to the icon on the lower banner? So not usable.
I use windows 10
2 display,s. ( in order to solve the problem I disconnected one display and cont. with one display. Restarted the computerand arduino. No result.
On a topic related to this issue I opened my preference file and removed all serial lines.
Also no result.
Any help and/or is much apreciated.
Regards ilioSS

The Serial monitor may be partly off screen. Try this

First, press Alt+Tab to pick the window you want to move. When the window is selected, press Alt+Space to open a small menu in the upper-left corner. Press the arrow key to select “Move,” and then press enter. Use the arrow keys to move the window where you want it onscreen, and then press Enter.

Hi UKHeliBob,

Thanks for your reply.
Meanwhile I changed to the arduino IDE rc2.0.0-rc3
here the monitor is working.
Thanks any way.
If for instance the rc-3 is not my floufor I will change to 2.8.19 again and your tip is more than welcome.

Upgrading to a later version of the classic IDE may not help if the Serial monitor is off the screen if its position is being read from preferences.txt

Here is the relevant line in my copy of preferences.txt

last.serial.location=1240,43,630,728

Note that you can only successfully edit preferences.txt when the IDE is not running because it is overwritten when the IDE is closed
