Hello, I use this program in windows 11 with compatibility XP Sp3. Allmost all works nomal but if I want to make a backup a little routine flaG with
%%HP: T(3)A(D)F(.);
\<< 'fLaG' PURGE { # 18366250820568048d # 0d } STOF
\>>
will be generated and in the 48GX display stands
EXECUTE COMMAND
EVAL STOP
No backup will be generated. Has anyone a solution?

Hello, I overcome the problem mentioned above. Do the following please.
1. download Conn4x_Build2361 from Williams site http://www.debug4x.com
2. unzip the file Conn4x_b2361.zip and copy the file Conn4x_b2361.exe
in your W11 installed directory
C:/Programme(x86)/Hewlett-Packard/Conn4x
3. do not rename it and use it with the complete name instead of Conn4x.exe
4. use Conn4x_b2361.exe with the compatibily mode XP SP3
5. make with Conn4x_b2361.exe a new shortcut on the desktop
6. if you want to get the help in your language for example German make
Conn4x.chm -> Conn4xUSA,chm and Conn4xGerman.chm -> Conn4x.chm
I do not have any porblems after my first experiments with this modifications
for backups, restore, screen capture and so on in the Windows 11
with HP 48GX.
Siegfried
