Tryed to use it for a simple project : the GUI is buggy, grouping task does not display correctly, copy paste does not update task grid correcty and so on. Unusable currently.

Existe un Bug con la definición de los calendarios, que ha persistido desde mucho tiempo. No es fácil trabajar con ellos y tampoco los guarda correctamente, a veces los elimina o cosas así. La idea es buena pero simplemente no es práctico definir un calendario que desaparecerá, además de que no todos trabajamos con el mismo horario.

The java based gui of this app is its downfall

If you're real PM , don't waste your time trying this kind of shitty app. It is all buggy especially the task screen. The bugs touches sensitive and important modules used by any PM regardless the project size. I tried to use it (as a kind of support for open-source projects) for experimental project, but it fails from the first 4 tasks and because of this we decide to trash it forever. Personally, honestly I feel that it is not practical at all.

Useful program but the GUI lacks major features, which makes working very inefficient Such as - All tasks are expanded when opening a project, current view cannot be saved - Strange scrolling behaviour, zooming by mousewheel not working - GUI options are not saved and so on. I also had a look at the source code, almost no comments existing.

Has potential, but lacks any real support or even decent documentation. The "help" button takes you to a defunct website. The "community" support is months or years behind and often gives overly simplified answers to questions to make it look like they are doing something. Setting in this software have issues sticking. You may have to set a setting 5 times before it sticks. Tons of bugs. When changing a resources calendar, the software may recalculate a task to be a million days to complete. When copying a resource, if that resource is assigned anywhere, the copy will also be assigned. You cannot delete the copy's assignment without closing the application and reopening, then delete the resource assignment, then restart the software to see the change. Assigning calendars to a resource seems to work, but does not show correctly in the interface. The software often confuses hours with dollars so when a task costs 100,000 dollars, it is automatically scheduled to take 100,000 days to complete. It is clear that this software is being abandoned since these bugs have been present in the software for several months with no information on correcting them. Too bad, it has a lot of potential.
