XXHighEnd Model 0.9x-2 (solves anomalies at startup of a new version)

[PeterSt]

• When a new version has been installed, it always has been the intention to be able to restore the settings from a previous version;
  
  Right from the beginning this actually never worked. I was found now that this was caused by two MS bugs;
  1. Properties of a control (like a slider) can officially have a minimum setting. At such a restore the value of such a slider is zero at first, and because this is less than a set minimum setting of e.g. one, an error occurred.
  2. When such an error occurred, at a later saving of the settings (while in the mean time al had been reset to good values), nothing would be saved.
  These both together, would cause an answer of "Yes, restore" to have the question to restore the previous settings popup over and over, until a No was answered once. Not exactly the intention of course.
  If all is right, this now has been solved.
  Please let know if you still encounter anomalies in this area.
  
  
• Under Vista, each program not executed before, would imply the question "Can't confirm the publisher, Are you sure to run this software ?" (similar);
  Since quite a few programs are subject to this, and since they would run at "random" occasions including somewhere under the hood, it could even happen that the popup with the question was there without seeing it. Also, such a popup contains a checkbox "Always warn before this file is opened" (similar) and the checkbox is ticked by default. All together not the best thing for a new user not knowing what is happening (but for experienced users a problem evenso).
  
  Now, after the first running of XXHighEnd after a fresh install, all these programs are run in a dummy fashion, and once this sequence is passed, this should not bother again throughout the use of that version.
  Whether this indeed allows to see all these questions implied, including the possibility to untick that checkbox, is not sure.
  Please let know if this is not the case, hence things seem to hang under the hood, watring for you to answer to the popup concerned.
  The sequence of questions after a new install should just go within tenths of a second at you answering questions in either case. If nothing seems to happen anymore, something is wrong.
  
  
• Since 0.9x-1 it could happen that XXHighEnd started outside the boundaries of the screen.
  Also it could happen that the time slider extended to outside the right boundaries of the form.
  If all is right, both issues are solved.
  
  
• Since a few versions back it could happen that when playback (Attended) was commencing, clicking the Clear button would cause an error. Solved.
  
  
• Also since a few versions back, some of the means for loading tracks into the Playlist Area would not allow to load MP3 files anymore. Besides that, errors would occur attempting so. Solved.
  
  
• Support for AIF files has been added.
  Note that AIF files are the same as AIFF files, but origine (?) from Dos-like 8.3 files.
  In the Library Area AIF files will show as "(AIFF)".
  
  
• Since 0.9x-1 changing the position of the Q1 slider did not incur for an auto-restart of XXEngine3 at Attended (at Unattended it should not -> change and press Play). Solved.
