Disappointing-- does not recognize different forms of a word

I recently purchased this dictionary after reading through endless reviews and websites about the various options. The Collins version is billed as "the same as the ultralingua" version that sells for $10 less, but with a much more comprehensive selection of words. What they did not let me know is that it is in fact NOT like the ultralingua version. The Collins version does not recognize different forms of a word, such as conjugated forms, which makes looking up words difficult and a matter of guesswork to determine the correct spelling of the root word. The translations are also so brief (english and spanish) that I find myself wondering about the meanings even if I manage to find it in the dictionary.
