B4J Question Problem configuring path to Java library

Hi,
Using Windows 11
Just updated my old version of B4J to the latest version 10.30
Downloaded the latest Java library JDK 19.0.2 and unpacked it using 7-zip to c:\Java\jdk-19.0.2 folder
Opened the IDE and used Tools|Configure paths to point to c:\Java\jdk-19.0.2\bin\javac.exe
When I close that dialog and try to compile a program, I get a heap of errors in the compile dialog:
B4J Version: 10.30
Parsing code. (0.00s)
Java Version: 8
Building folders structure. (0.00s)
Compiling code. (0.01s)
Compiling layouts code. (0.01s)
Organizing libraries. (0.00s)
Compiling generated Java code. Error
System.Exception: Cannot find: C:\Java\jdk-11.0.1\jdk-11.0.1\bin\javac.exe
Please configure paths (Tools - Configure Paths).
at fe.a(Process A_0, Boolean A_1, DataReceivedEventHandler A_2,

Looked again in the Configure paths, and indeed it still points to the older path to jdk-11.0.1, the old version I used to use., which I deleted.
Seems to be stuck on that path, and wont accept the new one, even when all I do is change the path to the new one, close the Configure paths dialog and reopen it.

Any ideas would be appreciated
