Widget won't open when trying to work interactively.

[Checkwithgit]

Hi all Orange Lovers/Users,

When I first started using Orange 3 I could set up a workflow including data files, tables, PCA, Spectra widgets and many more and all of them could be opened repeatedly as I changed data anywhere in the flow and the changes would be automatically carried right through the workflow for easy visualisation and work. Recently, I could not use this feature of Orange as the widgets would only ever open once and you would have to replace them with other identical icons on the workflow.
What has happened???

Regarding this question - please cancel as I have just discovered the cause of the problem. I was just minimising the open widget screen instead of completely closing it. Works perfectly now.
