Hi Simon
Thank you for your support words
These are all known issues that of course will not happen in the new version 1.2.
For now, here are the workarounds:
1. Run the PixInsight core application.
2. Open the ATrousWaveletTransform (ATW) interface. Make sure that the Wavelet Layers is visible.
3. The noise reduction section isn't visible for now. Expand the ATW window vertically. Do it quite severely; let it occupy most of the available vertical space on the workspace.
3. Exit PixInsight, then run it again. Now the ATW window shows the noise reduction section. You can resize it to a reasonable height.
To prevent this problem, simply don't collapse the Wavelet Layers section. As I've said, this won't happen in version 1.2; I already have this bug fixed.
Now the problems with CurvesTransform, etc. This is also a bug, and of course it has been fixed in 1.2. This happens because you have exited the application with these windows shaded (you shade a window by clicking the "diode" button on its title bar). To prevent this, just take the precaution to unshade all processing windows before exiting PixInsight.
Sorry for the inconveniences. I am delaying the release of 1.2 because it comes with new functionality that requires thorough testing. I cannot work faster; I have to ask for more patience again...
