	The version presented here corrects this by introducing a new variable ''LetterTimeGap''. The float value entered for ''LetterTimeGap'' not only controls the timer (''llSetTimerEvent(LetterTimeGap)'') but is also used to populate PSYS_SRC_BURST_RATE and PSYS_SRC_MAX_AGE. This ensures that only one character is capable of being emitted before the particle system shutsdown. Furthermore, if the region is subject to time dilation, that dilation is passed through to the particle system rather than just effecting the timer. Any time dilation then remains proportional throughout those parts of the script that it effects most.		The version presented here corrects this by introducing a new variable ''LetterTimeGap''.

	In the original Particle XYText scripts (and indeed in many particle scripts circulating in-world) PSYS_SRC_MAX_AGE is erroneously set to 0.00. According to the LSL Wiki, "''Zero will give the particle system '''an infinite duration'''''". So, if you want the particle system to last for one second you set PSYS_SRC_MAX_AGE to "1.00", or "2.00" for two seconds and so on. But, if you set it to "0.00" it will continue pumping out particles at the rate defined in PSYS_SRC_BURST_RATE. However, as the emission of each individual character is controlled by a timer, we '''do not''' want an emission of infinite duration. What we want is an emmision of a most definately defined '''finite''' duration. The absolute maximum duration that we want for the particle system is one character ~ which clearly is the same float value that llSetTimerEvent() has been set to.

	Similarly, PSYS_SRC_BURST_RATE ~ "''the time interval, in seconds, between bursts of particles being emitted''" must not be less than the float value that llSetTimerEvent() has been set to. If the PSYS_SRC_BURST_RATE value is set to less than the llSetTimerEvent() value, then (PSYS_SRC_BURST_RATE * PSYS_SRC_BURST_PART_COUNT) emmisions will be made before the timer states that the next character in the string is due.
