           Summary: Solver Progress Dialog does not update while solver is
                    running (dialog remains frozen)
           Product: LibreOffice
           Version: 25.2.0.0 alpha0+
          Hardware: All
                OS: All
            Status: UNCONFIRMED

Screenshot showing the problem (frozen Progress dialog)

When running a solver model that takes a bit longer to finish, the Progress
dialog is shown to the user. However, after it is shown, it remains frozen and
is not updated.

Steps to reproduce
1) Open attachment 196153 (from bug 160062)
2) Go to the BinPacking sheet
3) Open the solver dialog Tools - Solver
4) Click Options and make sure the solver engine is either CoinMP or LpSolve
5) Click Solve
6) The Progress dialog will open, but it will not be repainted (see attached
screenshot)

I was able to reproduce this issue in gtk3 and Windows as well.

The Progress dialog works fine if the engine is DEPS or SCO (nlpsolver).
