[Qgis-developer] issue with QGIS via citrix

[Bo Victor Thomsen]

Wisse -

You might have some kind of network problem that pops up up between you 
Citrix server and the network share used to store the shape files. Try 
to create a share locally on the Citrix server and  save the shape files 
to this share instead.

The problem could be some kind of file access conflict with several 
users reading the shape file at the same time as another user is trying 
to edit the same shape-file. Try to edit the shape-file at a time when 
you are sure no other user are accessing the file.

When you have a multi-user, perhaps multi-edit environment as yours my 
strong, general advise is to store the data in a database like 
postgresql/postgis. Any file based format like shape-files, tab-files or 
spatialite is not suitable for this kind of environment.

The problem is that edits to vector shapefiles are not always saved, while the 'save edits' button is pressed and the changes are visible in the attribute tables. After reopening the vector file later, it appears that sometimes (randomly) the changes are lost/were not saved to the file. We save our files to a network drive. This works fine with other software and on our desktop systems. This problem only occurs on our thin client systems.
