On knime 3.7 build of 6th of december, when using it through a remote desktop :
when I click on the pen in a workflow annotation, the window becomes unresponsive and it is impossible to to any further action. KNIME can be closed, but workflows cannot be saved.
There’s (at least) two problems in 3.7.0 with the application freezing under Windows (due to the graphics subsystem running out of resources.) One can be seen in using a loop with a large number of iterations, and the other involves working with annotations when there are a fair number of nodes and/or annotations also in the workflow.
The former has a fix that has been merged into the 3.7.1 release, and so can be found in the nightly builds.
The second has a fix that is waiting in PR at the moment; it seems likely that a merge will not happen until the new year. Later today (perhaps by 21h GMT,) i can make a drop-in patch jar available similar to what i discuss in this post - Workflow freeze & graphics problems with KNIME 3.7
