configuration preset windows blank

[Berangere Deleglise]

Hi all,
I am experiencing a problem with the new version 1.3.40 which controls  
our zeiss axio observer. Whenever I create a group (eg filter set) and  
try to configure this group to create different configuration (eg  
FITC...); when I try to recall this configurations from the drop  
list,although the filters are changed properly, the window appears  
blank.Then when I try to edit the configuration the following error  
message appears: "to edit a preset please select the preset first then  
press edit".

We already experience that problem (blank window) with the previous  
version but we could still edit the configuration.

Does anyone knows why the configuration's window is unstable?

Attached the core log

Thanks for your help

This can be caused by one of the properties in the preset not exactly  
matching the value it was set too.  This happens most often with  
something like Halogen Lamp intensity, where setting it to a value  
results in a similar, but not identical value reported by the  
hardware.  It is very difficult for us to create different behavior.  
The best solution is to avoid such properties (in general, everything  
with a slider, but also other properties in which you can set a number  
with decimals) in a preset group.  Rather, make an individual group  
for each of these.

We'll see if we can re-create that behavior.  However, you can still  
edit the configuration file directly (with a text editor like notepad  
on Windows) to take out the problematic properties.

In this case, it would have been more helpful to see the configuration  
file.  If you send it I can possibly give you some advice on how to  
organize it differently.

It is best to keep the configuration as simple as possible.  I have  
seen many instances where people put way more properties than  
necessary in the preset groups, leading to more than necessary  
communication with the hardware (and accompanying delays) as well as  
issues like you describe.

Best,

Nico
