waitFor() method works unproperly.
For example, running the same data program by javac from command line ends smoothly with returning description of the errors. Running the javac through the waitFor() should also be completed without problems, with indicating a type of error. However, in some situations (not always evident), it can block
the whole program forever.Ctrl-C to quit the InfoExplorer, correct the data program, and try again. Use encodings that are present on the target computers, or such "safe" encodings as Cp1251.
When printing, content is always scaled to fit on one page.
This is done to prevent cases of currently less than perfect displaying the content during page breaks. For example, images may be divided between pages. This problem will be fixed in the future releases (free update for registered users).
Meanwhile, if number of pages is more than one, some visual scaling is applied. Setting minimal font size can partly compensate it.
In any case, you can use Export function to make HTML version of the required InfoPage and print it from your favorite browser.
