    Thanks, I have tried copying it to the new .ui file, but behavior is the same.

      Hmm it must be something with QT Creator
      itself or support libraries.

      Maybe you could clone your virtual machine and install/reinstall QT just to check if something is wrong.

      I will try to paste into a ubuntu Qt Creator just to check if linux version is happy with your file too.

      update:
      Opens file fine in qt 5.5 on ubuntu.

        Thank you for investigation. It may be the problem with VM, but I am not the person who manages it. Can it be the problem with Qt Creator config? If yes, what files should I look for?

          Well it seems to be a problem with QT Creator since the xml file seems valid and can be loaded in both win and linux.

          So I assume something wrong with the Creator installation.

          I am not aware of any config that would affect the reading of UI files as it is
          a integrated part of Creator.

          Would it be possible for you to create a snapshot of the WM and then reinstall qt?

            I have to ask administrators of the VM if it is possible. Many thanks for your time.

              It is possible to install qt with no root access

              http://www.qtcentre.org/threads/23225-Installing-Qt-without-root-privileges

              You could install a new qt to a new folder in /home and run it from there but to be on the safe side,
              it is best to have a backup of what you have now.

              One question.
              If you make a new UI file and then insert control to it, it will also start to crash Creator ?

                I created new UI form and could modify it without problems (eg. add buttons). However when I put the xml code from previous dialog freeze occurred again - so I suppose something is wrong with this form's nodes.

                  Just strange that the same xml works fine here.
                  But I guess if you can just recreate the dialogs and it works, it a fix.

                    I have found what was the real problem. This issue occurred only on Dialog windows. I set for them 'modality' - ApplicationModal and that was the problem I was looking for. After removing this property from xml file everything is fine.
                    It seems to be a bug.

                        After removing property "windowModality" freeze is not occurring again

                        <ui version="4.0" >
                         <class>CreateExecutionDialog</class>
                         <widget class="QDialog" name="CreateExecutionDialog" >
                          <property name="windowModality" >
                           <enum>Qt::ApplicationModal</enum>
                          </property>
                          <property name="geometry" >
                        ...
                        

                        System: CentOS 5.5
                        QT version: 4.2.1
