GANTTPROJECT very slow

Hello,
I have updated the last rev and GANTTPROJECT is very slow each time I create a new task or change a parameter.
Do you have the same issue?
Windows 11 Pro
Thank you

No, we don’t. Please share a screencast that demonstrates the issue and attach a sample file. It may also make sense to look at the Task Manager to see if there is any process that consumes CPU.

Thank you for your quick answer.
Difficult to show this with a screen shot.
For exemple, I select a duration of a task with the mouse. If I hit enter, I can modify the data, and if I clic again on enter, it take about 4 to 5 seconds before I can do anything else.
DODIX - Planning Déploiement.gan (31,4 Ko)

I didn’t ask for a screenshot, I asked for a screencast (video). I tried to change the duration of some tasks from this project, and it worked fine.

What GanttProject version are you using?
