I will work today on the odbxx API to make sure there are no memory leaks when you switch form one file to another. I talked to KO so he agreed that yo

Sorry to intervene there, but the FEs are usually compiled against libmidas.a . Therefore you have to compile midas, usually do a "make install" to update
the libmidas.a/so, then recompile the FEs. You probably forgot the "make install".

I confirm the problem is there (at least under MacOSX Safari) and I will take care of it.

|
Dear all,
Stefan wants to run an external EPICS driver process as a detached process and somehow "glue" it to midas to control it. Actually a
similar requirement led to the development of MIDAS in the '90s. We had too many configuration files lying around, to many process to control and interact |

Can you please update to the latest develop versiokn of midas, and clear your browser cache so that the updated JavaScript midas library is loaded. Should
be fixed by now. See attached screen shot where I changed every second value via the ODB editor.

Thanks for the fixes, which I all approve.
There is still a "follow_links" in midas_c_compat.h line 70 for Python. Probably Ben has to look into that. Also
