This page contains a brief, updated, listing of important new issues found in Migri after the date of the most current release and aims to help Migri users who have concerns about problems they may experience. The reported issues will be fixed in later releases.
Migri may crash on Linux when using File->Exit to close the application and immediately afterwards moving the mouse cursor into the 3dview.
|The Layout/2D Scalebar option also activates the model bounding box when in 3dview mode.||Open||2.0.0|
|Model bounding box Z-axis may show uneven numbers when Scaledepth > 1.0||Open||2.0.0|
|“Filter undefined” and “Filter out-of range vales” options for profiles do not work for the HC.flowrates property.||Open||2.0.0|
|Rotation point is reset when switching between 3d and 2d mode.||Open||2.0.0|
|"Auto-plot in 3Dview" option in Caserun results does not work yet.
Workaround: Use the preview window or right click to save as grid.
The "Save Property as..." option on Linux does not assign a subfix to the filename corresponding to the selected filetype filter (e.g .shp subfix for shape files).
This needs to be done manually by the user for now.
The "Tube with breaks" wells draw style is painted without breaks.
|Some types of annotations do not yet account for z-axis scaling/stretching. The labels may therefore be displayed in the wrong z-positions.
Workaround: Move layer stretching slider to left side (no stretching) and set View/Scale Depth to 1.0 to view labels in correct positions.
|Fixed in 2.0.1||2.0.0|

Workaround: Switch to "User labels" to any other option in the Selection Info toolbar menu before selecting points)
